tty: serial: msm: Add msm prefix to all driver functions
Make function naming consistent across this driver. Also rename msm_irq to msm_uart_irq. No functional changes. Signed-off-by: Ivan T. Ivanov <ivan.ivanov@linaro.org> Reviewed-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
